FIELD OF THE TECHNOLOGY

At least some embodiments disclosed herein relate to a networked system for passenger screening. For example, at least some embodiments disclosed herein relate to a network system for passenger screening for ridesharing services.

BACKGROUND

Ridesharing has become a pervasive mode of transportation in the United States and is growing throughout the world. A ridesharing service connects passengers with drivers or vehicles via a website or another type of application. Currently, several ridesharing services match customers and vehicles via mobile apps. Ridesharing services for automobiles can be referred to as ride-hailing services, and such services also are available for ridesharing with other types of vehicles including aircraft and watercraft.

Ridesharing services have become prevalent in less populated or poorer areas that are not regularly served by taxicabs. Also, ridesharing has become widespread because there is at least a perception that such services are less expensive than taxicab services. Also, ridesharing is beneficial because it has been shown to reduce drunk driving rates in some cities where such services operate.

One example problem with ridesharing is that it is at least perceived to be less safe than hailing a taxi or a professional ride service. However, steps are being made to overcome safety concerns as well as concerns of fraudulent ridesharing services. On the other hand, intoxicated, fraudulent, or belligerent customers can create problems for drivers. Also, tired, drunk, deceitful, or aggressive drivers can create problems for customers.

To protect drivers as well as customers, ridesharing services have been regulated in cities, states, and countries. And, in some jurisdictions, ridesharing has been banned due to safety concerns and possibly lobbying by taxi companies. Regulations for ridesharing services can include requirements for driver background checks, fares, the number of drivers, licensing, and driver wage.

DETAILED DESCRIPTION

At least some embodiments disclosed herein relate to a networked system for passenger screening. For example, at least some embodiments disclosed herein relate to a network system for passenger screening for ridesharing services. In some embodiments, a taxicab or a vehicle of a ridesharing service can take pictures or record a video of an approaching customer or passenger and generate a risk score of a person as a customer or passenger. The risk score can relate to whether or not a potential passenger is intoxicated. The score can even relate to an intoxication level of the customer as well as the mental state or stability of the customer. The score can relate to physical or cognitive impairment of the potential passenger, criminal history of the potential passenger and riding history of the potential passenger. The driver can be prompted, by the vehicle or a computing device within the vehicle, to refuse the customer or passenger when the risk score is above a threshold.

In some embodiments, a driver can look at sample images of passengers and give respective risk scores. A system of a ridesharing service can then use artificial intelligence (AI) to learn to provide risk scores similarly to the driver or to drivers of the service in general. The learning (or machine learning) can be done using a dataset such as sets of images of passengers and corresponding risk scores. For example, if a driver is given the opportunity to determine a risk score of a passenger by observing the passenger for a moment (e.g., using the ridesharing app of the system), what the driver observed can be similarly observed by a camera. The system cannot determine how a driver decides on a risk score; but, the system can train or adjust parameters of an AI technique, such as an artificial neural network (ANN) or a decision tree, to minimize the difference between the risk scores generated by the driver (or drivers in general) and the scores computed by the AI technique. Such machine learning can be considered supervised machine learning.

In some embodiments, a vehicle can include at least one camera, configured to record at least one image of a person approaching the vehicle. The at least one camera can also be configured to generate and send biometric data derived from the at least one image of the person. The vehicle can also include a computing system configured to receive the biometric data from the at least one camera and to determine a risk score of the person based on the received biometric data and an AI technique, such as an ANN or a decision tree. The received biometric data or a derivative thereof can be input for the AI technique. The computing system can also be configured to determine whether to notify a driver of the vehicle of the risk score based on the risk score exceeding a risk threshold. The vehicle can also include a user interface (which can be a part of the computing system), configured to output the risk score to notify the driver when the computing system determines the risk score exceeds the risk threshold.

In some embodiments, the computing system of the vehicle is configured to determine, via a ridesharing service app of a ridesharing service, biographical information of the person approaching the vehicle based on at least the received biometric data and a database of passengers of the ridesharing service. The database can store biographical information on registered passengers that are registered for the ridesharing service. And, the stored biographical information can include biometric characteristics of the registered passengers as well as at least one of criminal histories of the registered passengers, riding histories of the registered passengers, payment histories of the registered passengers, tipping histories of the registered passengers, or violation histories of the registered passengers, or any combination thereof.

In some embodiments, the computing system of the vehicle can be configured to determine the risk score of the person approaching the vehicle based on the received biometric data, the AI technique, and the determined biographical information of the person. The input for the AI technique can include the biometric data or a derivative thereof and/or the determined biographical information or a derivative thereof.

In some embodiments, the vehicle can include a plurality of cameras that face outwards from the vehicle in different directions to have a field of view that covers at least a semicircle in a horizontal plane relative to the vehicle. The plurality of cameras can include the at least one camera of the vehicle. In such embodiments and others, the plurality of cameras can have a field of view that covers at least a full circle (e.g., 360 degrees) in the horizontal plane to record at least one image of a person approaching the vehicle from any direction in the horizontal plane (e.g., see cameras 16 a, 16 b, 16 c, and 16 d of vehicle 10 shown in FIG. 1).

In some embodiments, the computing system of the vehicle can be configured to control whether to determine the risk score according to parameters related to the approach of the person approaching the vehicle. And, in such embodiments and others, the received biometric data (received by the computing system of the vehicle) can include information on a gait of the person approaching the vehicle. And, in such embodiments and others, the received biometric data can include information on a posture of the person approaching the vehicle. Also, in such embodiments and others, the received biometric data can include information on a gait of the person and information of a posture of the person approaching the vehicle. The received biometric data can also include information on facial characteristics of the person approaching the vehicle.

In some embodiments, the vehicle can include at least one sensor, configured to sense at least one non-visual biometric feature of the person approaching the vehicle. The at least one sensor can also be configured to generate and send non-visual biometric data derived from the at least one sensed non-visual biometric feature of the person. In such embodiments and others, the computing system can be configured to receive the non-visual biometric data from the at least one sensor and determine the risk score of the person based on the received biometric data, the received non-visual biometric data and the AI technique. The received non-visual biometric data or a derivative thereof can also be input for the AI technique.

In some embodiments, at least two cameras of the vehicle can be configured to record at least two images of a person approaching the vehicle. And, the at least two cameras can be configured to send biometric data derived from the at least two images of the person. In such examples, the computing system can be configured to receive the biometric data from the at least two cameras and determine a risk score of the person based on the received biometric data and an AI technique. Also, in such examples, the received biometric data or a derivative thereof can be used as input for the AI technique, and the computing system can be configured to determine whether to notify a driver of the vehicle of the risk score based on the risk score exceeding a risk threshold. And, in such embodiments, the vehicle can include a user interface, configured to output the risk score to notify the driver when the computing system determines the risk score exceeds the risk threshold.

In general, an AI technique (e.g., an ANN or decision tree) may be trained using a supervised method where the parameters in the AI technique are adjusted to minimize or reduce the error between known outputs resulted from respective inputs and computed outputs generated from applying the inputs to the AI technique. Examples of supervised learning/training methods include reinforcement learning, and learning with error correction.

Alternatively, or in combination, an AI technique may be trained using an unsupervised method where the exact outputs resulting from a given set of inputs are not known before the completion of training. The AI technique can be trained to classify an item into a plurality of categories, or data points into clusters. Multiple training algorithms can be employed for a sophisticated machine learning/training paradigm.

In some embodiments, the computing system of the vehicle is configured to train the AI technique using supervised learning. The input for the supervised learning of the AI technique can include image data of images of sample passengers or customers and risk scores determined by the driver for the images of the sample passengers or customers. This way the AI technique can be customized and trained for the driver specifically. Also, the input for the supervised learning of the AI technique can include image data of images of sample passengers or customers and risk scores determined by drivers of the ridesharing service for the images of the sample passengers or customers. This way the AI technique can be enhanced and trained for the drivers of the service in general. The input for the supervised learning of the ANN can also include non-visual biometric information (e.g., voice recording) of the sample passengers or customers and risk scores determined by the driver (or drivers of the service in general) for the non-visual biometric information of the sample customers or passengers.

As shown in FIG. 1, the vehicle 10 includes a body 12 and the body includes a roof 14 and four cameras (see cameras 16 a, 16 b, 16 c, and 16 d) facing outwards from the vehicle. The cameras 16 a to 16 d are shown as being on or included in the roof 14 of the vehicle 10. However, it is to be understood that such cameras can be located and attached to the vehicle 10 at any part of the vehicle as long as the cameras are positioned at different sides of the vehicle and cover at least a full circle in a horizontal plane relative to the vehicle to record at least one image of a person approaching the vehicle from any direction in the horizontal plane. Also, as shown in FIG. 1, a horizontal plan relative to the vehicle 10 is being looked down upon. In other words, FIG. 1 depicts a top view of the vehicle 10 and of the horizontal plane. Also, as shown in FIG. 1, each camera of the cameras 16 a to 16 d is a panorama camera configured to record images from a wide horizontal angle. Also, as shown, each camera of the cameras 16 a to 16 d is configured to record images from a wide horizontal angle equal to or exceeding one hundred and eighty degrees.

In some embodiments, the vehicle 102 includes at least one sensor (e.g., see sensors 114 a to 114 b). The at least one sensor can be configured to sense at least one non-visual biometric feature of the person approaching the vehicle 102. And, the at least one sensor can be configured to send non-visual biometric data derived from the at least one sensed non-visual biometric feature of the person.

For example, the risk score and accompanying information can be sent, by the vehicle computing system 104 (such as via the RSSS client 106), to the RSSS server(s) 150 via a part of the network(s) 122.

In such embodiments and others, the vehicle computing system 104 (such as via the RSSS client 106) can be configured to receive and process data (e.g., such as data including instructional data for the vehicle and its systems and/or data related to biographical information of the approaching person stored in the database of passengers) from the RSSS via the wide area network. For example, the data can be received, by the vehicle computing system 104 (such as via the RSSS client 106), from the RSSS server(s) 150 via a part of the network(s) 122, and then the received data can be processed for inclusion in other processing steps described herein. The received data can include information derived from at least linked risk score data, image data, sensed non-visual biometric data, temporal data, position data, or other contextual data sent from the vehicle 102 or other vehicles (e.g., see vehicles 130 to 132) regarding the person approaching the vehicle. In some embodiments, the derivation of the received data and/or the later processing of the received data can be according to an AI technique, and the AI technique can be trained by a computing system of the RSSS, the vehicle 102, or a mobile device of the driver (e.g., see mobile devices 140 to 142). In such embodiments and others, the vehicle 102 can include a user interface (such as a graphical user interface) configured to provide at least part of the received and processed data to a user of the vehicle (e.g., see other components 216 of vehicle 202 depicted in FIG. 3, which can include a GUI).

The vehicle 102 includes vehicle electronics, including at least electronics for the controllable parts of the body, the controllable parts of the powertrain, and the controllable parts of the power steering. The vehicle 102 includes the controllable parts of the body and such parts and subsystems being connected to the body control module 108. The body includes at least a frame to support the powertrain. A chassis of the vehicle can be attached to the frame of the vehicle. The body can also include an interior for at least one driver or passenger. The interior can include seats. The controllable parts of the body can also include one or more power doors and/or one or more power windows. The body can also include any other known parts of a vehicle body. And, the controllable parts of the body can also include a convertible top, sunroof, power seats, and/or any other type of controllable part of a body of a vehicle. The body control module 108 can control the controllable parts of the body. Also, the vehicle 102 also includes the controllable parts of the powertrain. The controllable parts of the powertrain and its parts and subsystems are connected to the powertrain control module 110. The controllable parts of the powertrain can include at least an engine, transmission, drive shafts, suspension and steering systems, and powertrain electrical systems. The powertrain can also include any other known parts of a vehicle powertrain and the controllable parts of the powertrain can include any other known controllable parts of a powertrain. Also, power steering parts that are controllable can be controlled via the power steering control unit 112.

The plurality of sensors (e.g., see sensors 114 a to 114 b) and/or the plurality of cameras (e.g., see cameras 118 a to 118 b) of the vehicle 102 can include any type of sensor or camera respectively configured to sense and/or record one or more features or characteristics of the surroundings of the vehicle 102, such as a person approaching the vehicle in its surrounds. A sensor or a camera of the vehicle 102 can also be configured to generate data corresponding to the one or more features or characteristics of the surroundings of the vehicle according to the sensed and/or recorded feature(s) or characteristic(s). A sensor or a camera of the vehicle 102 can also be configured to output the generated data corresponding to the one or more features or characteristics. Any one of the plurality of sensors or cameras can also be configured to send, such as via the CAN bus 120, the generated data corresponding to the one or more features or characteristics to the vehicle computing system 104 or other electronic circuitry of the vehicle 102. The sending of the data to other electronic circuitry of the vehicle 102 can be useful when an aggressive person or a known threat actor is approaching the vehicle. For example, the data or a derivative thereof can be sent to the body control module 108 to lock the doors, the powertrain control module 110 to start the engine, and/or the power steering control unit 112 to turn wheels in a direction moving away from a parked position of the vehicle, in response to an aggressor or threat actor approaching the vehicle.

A set of mechanical components for controlling the driving of the vehicle 102 can include: (1) a brake mechanism on wheels of the vehicle (for stopping the spinning of the wheels), (2) a throttle mechanism on an engine or motor of the vehicle (for regulation of how much gas goes into the engine, or how much electrical current goes into the motor), which determines how fast a driving shaft can spin and thus how fast the vehicle can run, and (3) a steering mechanism for the direction of front wheels of the vehicle (for example, so the vehicle goes in the direction of where the wheels are pointing to). These mechanisms can control the braking (or deacceleration), acceleration (or throttling), and steering of the vehicle 102. The driver can indirectly control these mechanisms by UI elements (e.g., see other components 216 of vehicle 202 shown in FIG. 3 that can be operated upon by the user, which are typically the brake pedal, the acceleration pedal, and the steering wheel. The pedals and the steering wheel are not necessarily mechanically connected to the driving mechanisms for braking, acceleration and steering. Such parts can have or be proximate to sensors that measure how much the driver has pressed on the pedals and/or turned the steering wheel. The sensed control input is transmitted to the control units over wires (and thus can be drive-by-wire). Such control units can include body control module 108 or 220, powertrain control module 110 or 222, power steering control unit 112 or 224, battery management system 226, etc. Such output can also be sensed and/or recorded by the sensors and cameras described herein as well (e.g., see sensors 114 a to 114 b or 217 a to 217 b and cameras 118 a to 118 b or 219 a to 219 b). And, the output of the sensors and cameras can be further processed, such as by the RSSS client 106, and then reported to the server(s) 150 of the RSSS for cumulative data processing of contextual data related to the person approaching the vehicle.

In a vehicle, such as vehicle 102 or 202, a driver can control the vehicle via physical control elements (e.g., steering wheel, brake pedal, gas pedal, paddle gear shifter, etc.) that interface drive components via mechanical linkages and some electro-mechanical linkages. However, more and more vehicles currently have the control elements interface the mechanical powertrain elements (e.g., brake system, steering mechanisms, drive train, etc.) via electronic control elements or modules (e.g., electronic control units or ECUs). The electronic control elements or modules can be a part of drive-by-wire technology. Drive-by-wire technology can include electrical or electro-mechanical systems for performing vehicle functions traditionally achieved by mechanical linkages. The technology can replace the traditional mechanical control systems with electronic control systems using electromechanical actuators and human-machine interfaces such as pedal and steering feel emulators. Components such as the steering column, intermediate shafts, pumps, hoses, belts, coolers and vacuum servos and master cylinders can be eliminated from the vehicle. There are varying degrees and types of drive-by-wire technology. Vehicles, such as vehicles 102 and 202, having drive-by-wire technology can include a modulator (such as a modulator including or being a part of an ECU and/or an advance driver assistance system or ADAS) that receives input from a user or driver (such as via more conventional controls or via drive-by-wire controls or some combination thereof). The modulator can then use the input of the driver to modulate the input or transform it to match input of a “safe driver”.

FIG. 5 illustrates a flow diagram of example operations of method 400 that can be performed by aspects of the vehicle 10 depicted in FIG. 1 as well as the networked system 100 depicted in FIGS. 2 to 4, in accordance with some embodiments of the present disclosure. For example, the method 400 can be performed by a computing system and/or other parts of any vehicle and/or mobile device depicted in FIGS. 1 to 4.

In FIG. 5, the method 400 begins at step 402 with recording, by at least one camera of a vehicle (e.g., see cameras 16 a to 16 d, cameras 118 a to 118 b, and cameras 219 a to 219 b), at least one image of a person approaching the vehicle (e.g., see vehicles 10, 102, and 202). Also, in some embodiments, step 402 can include recording, by at least one camera of a mobile device (e.g., see mobile devices 140 to 142 and 302), at least one image of a person approaching the vehicle. At step 404, the method 400 continues with sending, by the camera(s), biometric data derived from the at least one image of the person.

At step 406, the method 400 continues with sensing, by at least one sensor of the vehicle (e.g., see sensors 114 a to 114 b and 217 a to 217 b), at least one non-visual biometric feature of the person approaching the vehicle. Also, in some embodiments, step 406 can include sensing, by at least one sensor of a mobile device, at least one non-visual biometric feature of the person approaching the vehicle. At step 408, the method 400 continues with sending, by the sensor(s), non-visual biometric data derived from the non-visual biometric feature(s).

At step 410, the method 400 continues with receiving, by a computing system of the vehicle (e.g., see computing systems 104 and 204) or of a mobile device, the biometric data from the camera(s) and/or sensor(s). At step 412, the method 400 continues with determining, via an app of a ridesharing service, biographical information of the person approaching the vehicle based on at least the received biometric data and a database of passengers of the ridesharing service. At step 414, the method 400 continues with determining, by the computing system, a risk score of the person based on an AI technique (such as including an ANN and/or a decision tree) and the received biometric data and/or the determined biographical information. At step 416, the method 400 continues with determining whether or not the risk score exceeds a risk threshold. When the risk score exceeds the risk threshold, the method 400 at step 418 continues with outputting, by a UI of the vehicle (e.g., see other components 216), the risk score to notify the driver of the risk score for the person approaching the vehicle. When the risk score does not exceed the risk threshold, the method 400 at step 420 continues with sensing, by the camera(s) and/or the sensor(s), for a person approaching the vehicle. Such that when a person is sensed approaching the vehicle, the camera(s) can record image(s) of the person at step 402 and/or the sensor(s) can sense non-visual biometric feature(s) of the person at step 406.

Also, in some embodiments, step 410 can include receiving, by a computing system of a mobile device, the biometric data from the camera(s) and/or sensor(s). In such embodiments, at step 412, the method 400 can include determining, via an app of a ridesharing service rendered via the mobile device, biographical information of the person approaching the vehicle based on at least the received biometric data and a database of passengers of the ridesharing service. At step 414, the method 400 can include determining, by the computing system of the mobile device, a risk score of the person based on an AI technique (such as including an ANN and/or a decision tree) and the received biometric data and/or the determined biographical information. At step 416, the method 400 can include determining, via the computing system of the mobile device, whether or not the risk score exceeds a risk threshold. When the risk score exceeds the risk threshold, the method 400 at step 418 can include outputting, by a UI of the mobile device (e.g., see other components 316), the risk score to notify the driver of the risk score for the person approaching the vehicle. When the risk score does not exceed the risk threshold, the method 400 at step 420 can include sensing, by the camera(s) and/or the sensor(s) of the mobile device, for a person approaching the vehicle. Such that when a person is sensed approaching the vehicle, the camera(s) of the mobile device can record image(s) of the person at step 402 and/or the sensor(s) of the mobile device can sense non-visual biometric feature(s) of the person at step 406.

FIG. 6 illustrates a flow diagram of example operations of method 500 that can be performed by aspects of the vehicle 10 depicted in FIG. 1 as well as the networked system 100 depicted in FIGS. 2 to 4, in accordance with some embodiments of the present disclosure. For example, the method 500 can be performed by a computing system and/or other parts of any vehicle and/or mobile device depicted in FIGS. 1 to 4.

As shown, the method 500 includes the steps of method 400 and additional steps 502 and 504. Step 502 can occur subsequent to step 410 and depend on step 410 of method 400. At step 410, the method 500 includes the receiving, by the computing system of the vehicle (or of the mobile device of the driver), the biometric data from the camera(s) and/or sensor(s). At step 502, the method 500 continues controlling, by the computing system, whether to determine the risk score. The control or determination of whether to determine the risk score can be according to parameters related to the approach of the person approaching the vehicle. If it is determined to determine a risk score, then the method 500 continues with step 412 (the determining of the biographical information of the person approaching the vehicle) and/or step 414 (the determining of the risk score of the person based on the AI technique) of method 400 and so on. At step 504, the method 500 continues with sensing, by the camera(s) and/or the sensor(s), for a person approaching the vehicle. Such that when a person is sensed approaching the vehicle, the camera(s) can record image(s) of the person at step 402 and/or the sensor(s) can sense non-visual biometric feature(s) of the person at step 406.

In some embodiments, it is to be understood that the steps of methods 400 and 500 can be implemented as a continuous process such as each step can run independently by monitoring input data, performing operations and outputting data to the subsequent step. Also, such steps for each method can be implemented as discrete-event processes such as each step can be triggered on the events it is supposed to trigger and produce a certain output. It is to be also understood that each figure of FIGS. 5 to 6 represents a minimal method within a possibly larger method of a computer system more complex than the ones presented partly in FIGS. 2 to 4. Thus, the steps depicted in each figure of FIGS. 5 to 6 can be combined with other steps feeding in from and out to other steps associated with a larger method of a more complex system.

It is to be understood that a vehicle described herein can be any type of vehicle unless the vehicle is specified otherwise. Vehicles can include cars, trucks, boats, and airplanes, as well as vehicles or vehicular equipment for military, construction, farming, or recreational use. Electronics used by vehicles, vehicle parts, or drivers or passengers of a vehicle can be considered vehicle electronics. Vehicle electronics can include electronics for engine management, ignition, radio, carputers, telematics, in-car entertainment systems, and other parts of a vehicle. Vehicle electronics can be used with or by ignition and engine and transmission control, which can be found in vehicles with internal combustion powered machinery such as gas-powered cars, trucks, motorcycles, boats, planes, military vehicles, forklifts, tractors and excavators. Also, vehicle electronics can be used by or with related elements for control of electrical systems found in hybrid and electric vehicles such as hybrid or electric automobiles. For example, electric vehicles can use power electronics for the main propulsion motor control, as well as managing the battery system. And, autonomous vehicles almost entirely rely on vehicle electronics.

Some portions of the preceding detailed descriptions have been presented in terms of algorithms and symbolic representations of operations on data bits within a computer memory. These algorithmic descriptions and representations are the ways used by those skilled in the data processing arts to most effectively convey the substance of their work to others skilled in the art. An algorithm is here, and generally, conceived to be a self-consistent sequence of operations leading to a desired result. The operations are those requiring physical manipulations of physical quantities. Usually, though not necessarily, these quantities take the form of electrical or magnetic signals capable of being stored, combined, compared, and otherwise manipulated. It has proven convenient at times, principally for reasons of common usage, to refer to these signals as bits, values, elements, symbols, characters, terms, numbers, or the like.

It should be borne in mind, however, that all of these and similar terms are to be associated with the appropriate physical quantities and are merely convenient labels applied to these quantities. The present disclosure can refer to the action and processes of a computer system, or similar electronic computing device, that manipulates and transforms data represented as physical (electronic) quantities within the computer system's registers and memories into other data similarly represented as physical quantities within the computer system memories or registers or other such information storage systems.

The present disclosure also relates to an apparatus for performing the operations herein. This apparatus can be specially constructed for the intended purposes, or it can include a general-purpose computer selectively activated or reconfigured by a computer program stored in the computer. Such a computer program can be stored in a computer readable storage medium, such as any type of disk including floppy disks, optical disks, CD-ROMs, and magnetic-optical disks, read-only memories (ROMs), random access memories (RAMs), EPROMs, EEPROMs, magnetic or optical cards, or any type of media suitable for storing electronic instructions, each coupled to a computer system bus.

The algorithms and displays presented herein are not inherently related to any particular computer or other apparatus. Various general-purpose systems can be used with programs in accordance with the teachings herein, or it can prove convenient to construct a more specialized apparatus to perform the method. The structure for a variety of these systems will appear as set forth in the description below. In addition, the present disclosure is not described with reference to any particular programming language. It will be appreciated that a variety of programming languages can be used to implement the teachings of the disclosure as described herein.

The present disclosure can be provided as a computer program product, or software, that can include a machine-readable medium having stored thereon instructions, which can be used to program a computer system (or other electronic devices) to perform a process according to the present disclosure. A machine-readable medium includes any mechanism for storing information in a form readable by a machine (e.g., a computer). In some embodiments, a machine-readable (e.g., computer-readable) medium includes a machine (e.g., a computer) readable storage medium such as a read only memory (“ROM”), random access memory (“RAM”), magnetic disk storage media, optical storage media, flash memory components, etc.
